The numerous hydroxyl groups available in cyclodextrins are active sites that can form different types of linkages. They can be crosslinked with one another, or they can be derivatized to produce monomers that can form linear or branched networks. Moreover, they can form inclusion complexes with polymers and different substrates, modifying their… (More)

The study of antioxidants and radicals has always been a complex task due to the special characteristics of these species such as reactions at low concentrations and short half-lives. Current techniques do not always produce good results and in some cases they can only be applied in chemical models. From this point of view, the development of electron spin… (More)

Electron spin resonance (ESR), called also electron paramagnetic resonance (EPR) together with the spin trapping technique, has allowed us to study and understand how free radicals are involved in various pathologies. In this review, the importance of spin trapping technique in the study of diseases such as cancer, diabetes, hypertension and parasitic… (More)

Fumonisins are a group of mycotoxins found in various foods whose consumption is known to be harmful for human health. In this study, we evaluated the ability of three polymers (Polyvinylpolypyrrolidone, PVPP; a resin of N-vinyl-2-pyrrolidinone with ethylene glycol dimethacrylate and triallyl isocyanurate, PVP-DEGMA-TAIC; and poly(acrylamide-co-ethylene… (More)

Two families of 5-nitroindazole derivatives were electrochemically studied in an aprotic solvent using cyclic voltammetry (CV) technique. The produced nitro-anion radical species were characterized using electron spin resonance spectroscopy (ESR). Also, we examined the interaction between the radical species generated from nitroindazole derivatives and… (More)
